Was McCartney the first to work "Indian"-sounding licks and riff into pop bass lines?

I'm not exactly a Beatles connaisseur (don't like the way the vocals sound in most of their songs) and finally came across the video for "Rain" on youtube.com, and was instantly able to name a few songs I like that obviously ripped Paul's line off a bit.
I know using the Mixolydian scale to create "Indian"-sounding bass lines to spice up songs has become pretty much a bass staple, but was McCartney the first to use this approach? Discuss!
